GREY CORRELATION ANALYSIS OF STRUCTURAL STRENGTH FORMATION OF SOFT DREDGER FILL

Using soft dredger fill in Tianjin Binhai New Area as materials, grey correlation analysis of structural strength of soft dredger is carried out after structural strength formed under different confining pressure, deviator pressure, and drainage condition. The results show that many factors can cause the growth of structural strength of soft dredger. The drainage is the critical influence factor. For the soft dredger fill with weaker initial structural strength, the influence of the confining pressure on the growth of structural strength is greater than that of deviator pressure. For the soft dredger fill has stronger initial structural strength, the influence of the deviator pressure is greater than confining pressure.
